Abstract: The soft bodied structures and systems for controlling such devices are described herein. The soft bodied structures can, through a series of soft hydraulic actuators, move from a first position to a second position by a somersaulting motion. The system can include connecting to a first contact point of the surface using a surface attachment. The rigidity of the controllably resistive material can then be increased. The medial hydraulic actuators can be actuated to expand the exterior medial surface, creating a bend. The device can then attach to a second contact point using the surface attachment and the end portion actuator of the unattached end portion. Then, the surface attachment of the first attached end portion can detach. The medial hydraulic actuators and the controllably resistive material can then relax, followed by detaching the surface attachment of the second attached end portion.

Abstract: An electrically powered, self-propelled cart for safely delivering heavy loads, such as concrete, within job sites with unlevel, irregular, or sloped terrain. A cargo bucket is tiltable over front drive wheels for transporting and dumping cargo. Electric drive motors associated with a transaxle propel wheels at a selectable speed in response to an electric control module.

The sensor may be a linear potentiometer, a rotary differential transformer or a rotary encoder or shaft encoder measuring angular displacement. Extreme steering displacements will electrically reduce cart speed notwithstanding the previous speed setting chosen by the operator through the steering column.
